Community Gmail server with auto-auth: search, read and send email via MCP.
MailX Email Deliverability is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Check SPF/DKIM/DMARC/BIMI, blacklists, SMTP/IMAP; DNS lookups; generate email DNS records.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http mailx-email-deliverability-mcp https://themailx.com/mcp
# 2 — ask your agent for something these tools do
# spf_check, dkim_check, dmarc_check and 13 more
MailX Email Deliverability costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http mailx-email-deliverability-mcp https://themailx.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
16 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Check if a domain has a valid SPF (Sender Policy Framework) DNS record. SPF specifies which mail servers are authorized to send email on behalf of a domain.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain_name | string | yes | The domain to check SPF records for, e.g. example.com |
Check if a domain has a valid DKIM (DomainKeys Identified Mail) DNS record for a given selector. DKIM allows the receiver to verify that an email was sent by the domain owner.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain_name | string | yes | The domain to check DKIM records for, e.g. example.com |
| dkim_selector | string | yes | The DKIM selector to look up, e.g. google, default, selector1 |
Check if a domain has a valid DMARC (Domain-based Message Authentication, Reporting & Conformance) DNS record. DMARC tells receiving servers what to do with emails that fail SPF or DKIM checks.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain_name | string | yes | The domain to check DMARC records for, e.g. example.com |
Check if a domain has a valid BIMI (Brand Indicators for Message Identification) DNS record. BIMI allows brands to display their logo next to authenticated emails in supporting email clients.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| domain_name | string | yes | The domain to check BIMI records for, e.g. example.com |
Generate a DMARC DNS record for a domain. Returns the record name, value, and type ready to be added to DNS.
| Parameter | Type | Required | Notes |
|---|---|---|---|

| string | yes | The email address to receive DMARC aggregate reports, e.g. dmarc@example.com | |
| dmarc_policy | string | yes | The DMARC policy: none (monitor only), quarantine (mark as spam), or reject (block entirely) |
Generate an SPF DNS record for a domain based on the email provider being used. Returns the record name, value, and type ready to be added to DNS.
| Parameter | Type | Required | Notes |

| provider | string | yes | The mail provider identifier, e.g. google, mailgun, sendgrid, postmark, amazon-ses |
| hard_fail_boolean | boolean | yes | If true, uses strict -all policy (reject unauthorized senders). If false, uses soft ~all (mark but deliver). |

|---|---|---|---|
| host | string | yes | The SMTP server hostname, e.g. smtp.gmail.com |
| port | integer | yes | The SMTP port number, e.g. 587 for TLS, 465 for SSL, 25 for unencrypted |

| password | string | yes | The SMTP password or app-specific password |
| encryption | string | yes | The encryption protocol: ssl, tls, or none |
| from_email | string | no | Optional sender email address for sending a test email |

- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install MailX Email Deliverability or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish MailX Email Deliverability can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
